Where is the best location to apply fertilizer to fruit trees?
When applying supplemental fertilizer to fruit trees, it is important to understand that nutrient uptake relies primarily on the root hairs.
Fertilizer should be applied mainly at the outer edge of the tree canopy's projection (the drip line) or slightly beyond it. Avoid applying it too close to the trunk, as the area near the trunk contains mostly thick, structural roots with few fine roots or root hairs, making nutrient absorption inefficient.
Regarding application depth, follow these principles: apply fertilizer deeper for trees with deep root systems and shallower for those with shallow root systems. Organic fertilizers decompose slowly but provide nutrients over a longer period, so they can be applied deeply; conversely, chemical fertilizers are highly mobile and can be applied at a shallower depth. For example, when applying organic fertilizer to deep-rooted trees like pears, the depth should be 40–60 cm, whereas for shallow-rooted trees like plums, it should be 30–40 cm.
After fertilizing, spraying a "New High-Lipid Film" (a protective coating agent) can enhance fertilizer efficacy.
In orchards with closed canopies or high-density planting, fertilizer can be applied shallowly between rows or between trees. Care should be taken to avoid damaging major roots; this ensures maximum fertilizer efficacy and utilization, ultimately leading to increased yields and higher returns.
